    New Cold Start Injector / Valve Repairs & Replacement in Hamilton

    What does the cold start injector do?Cold start valve repairs hamilton

    In order engines the cold start injector (or cold start valve) allows your car’s engine to start smoothly and heat up quickly when it is cold. This allows for improved performance, idle speeds and fuel consumption on cold winter’s mornings. It also provides the added benefit of allowing the fuel rail to be kept under low pressure when the car isn’t running.

    The cold start injector is located on your engine’s intake manifold. When low engine temperatures are detected upon ignition, your car’s onboard computer will tell the cold start valve to inject more fuel into the engine. The increased combustion will allow your engine to heat up quickly.

    Problems with the cold start injector are usually caused by electrical issues such as faulty fuses, faulty wiring or a damaged control module. However, in some cases, the actual valve can become stuck or damaged. If the cold start injector fails, you may have trouble starting your car, or achieving correct engine temperatures and idle levels when the engine is cold.


    Symptoms of a faulty cold start valve:

    • Engine struggles to start – A faulty cold start injector may make it difficult to start your engine on a cold day. The car may take several attempted ignitions before the engine is finally able to turn over.
    • Engine stalling – After your engine starts, you may experience stalling while you drive. This will either occur at higher RPMs or when you take your foot off the pedal.
    • Rough idle – Your engine may produce loud noises or even vibrations when you are idling. This will happen as your car struggles to reach optimum running temperatures.
